Thank you for confirming that _refreshBorders is an internal method.
The code was written a long time ago by someone else. I haven’t encountered any issues even after removing that function, and we are also using render() in our implementation. As I am new to Handsontable, I’m unsure about the function’s specific purpose. Based on my search, I understand that _refreshBorders was used to refresh cell borders specifically, while render() refreshes the entire table.
I just want to make sure my understanding is correct. Is there any additional functionality that _refreshBorders provided that render() does not cover?
